Stopwatch & Timer
A simple stopwatch with lap timing — start, pause, record laps, and reset, all in your browser.
How to use the Stopwatch
Click "Start" to begin timing. Click "Lap" at any point to record a split time without stopping the clock — useful for tracking segments during a run, workout, or task. Click "Start" again (it becomes "Pause") to pause the timer, and "Reset" to clear everything and start fresh.
Common uses for a stopwatch
A browser-based stopwatch is handy for timing workouts, cooking, study sessions, presentations, sports practice, or any activity where you want to track elapsed time and compare lap splits without needing a separate physical stopwatch or app.
Frequently asked questions
How accurate is this stopwatch?
The stopwatch updates to tenths of a second and is accurate for everyday timing purposes like workouts and cooking. For scientific or highly precise timing needs, a dedicated instrument may be more appropriate.
Does the timer keep running if I switch tabs?
Yes, as long as the browser tab remains open (even in the background), the stopwatch continues running accurately.
Is my lap data stored anywhere?
No. This tool is part of the Toolyard collection of free, browser-based utilities. All timing happens locally in your browser — nothing is uploaded to or stored on a server, and lap times reset when you refresh the page.
